The NEW William Optics RedCat 51 APO is a 51mm f/4.9 Petzval refractor that includes synthetic fluoride (FPL53 and FPL51) glass elements for a full frame, flat field image.
Provides high resolution images when used for astrophotography or wildlife photography.
It's fast f/4.9 focal ratio and compact size makes it ideal for convenient wide field astrophotography or piggybacking.
Incorporates a smooth helical focuser, a field rotator graduated by degree, a slot for 48mm filters and a reversible dovetail for either Vixen style* or Arca-Swiss mounting.
* Some customers have found William Optics' Vixen style dimension a little too narrow for their mount's saddle so you might need to fit a different dovetail.
